I just today created a new area adjacent to an earlier scenery area of mine in an effort to expand the original. Unfortunately along the northern border I'm seeing a few tiles of low res default scenery that should be the high res scenery I just added. For some reason (and it's probably my fault but I don't know why) separate created scenery projects don't want to play nice with each other.
There is probably a good explanation for this and I need to go over the steps to add new areas so they properly work with older created areas, but I really was under the impression that separate areas created with Geoconvert would just work seamlessly with each other. Obviously they don't, but I will reexamine the tutorials and posts to see what I'm missing.
I have added a 1m high res area that is completely within the borders of a 2m res area ( a city within a larger area) and it works perfectly. To repeat, the issue I'm seeing is getting areas that overlap to some degree to work seamlessly together without having low res default scenery show up.
So, you're not alone...
Exact same issue here. Of the whole area, Hidef tiles appear when I fly over sometimes, and sometimes disappear also, and in the overlap it's a switch between hires tiles.
